R.I., a corporation of New York Filed Mar. 23, 1964, Ser. No. 353,767 9Claims. (Cl. 49-381) The present invention relates to an entranceconstruction. More particularly the present invention relates to anentrance construction that comprises a door assembly and frame therefor,the door assembly and frame including horizontal and vertical membersthat are formed of a thin gauge metallic material that is roll formed toa tubular configuration and that is secured in position by an interiorlock seam.

Metal materials for use in commercial entrance constructions are wellknown and for many year-s the members that defined such construct-ionshave preferably been formed of extruded aluminum. Commercial entranceconstructions constructed of aluminum have been employed with somedegree of success. However, aluminum does have its deficiencies in thatit has been known to pit and discolor, particularly when colors otherthan the natural color of the metal is applied to the surface thereof.It is known that stainless steel is a most desirable material for use indoor constructions because of the inherent characteristics of the metal.steel has not been practical for use in commercial entrance constructionbecause of the relatively high cost involved in the fabrication thereof.Prior to the instant invention the heretofore known stainless steel doorconstructions included an inner filler on which the stainless steelmetal material was shaped and formed. This resulted in an unusuallydurable construction but this form of door was also extremely heavy andexpensive to fabricate.

The present invention includes an entrance door construction that isfabricated of a stainless steel material but that eliminates theheretofore known objectionable features of stainless steel. In thepresent invention, a relatively thin gauge stainless steel is utilized,the individual members that define the entrance construction being rollformed and locked in place by interlocking the longitudinal edgesthereof to define an interior lock seam. Since stainless steel is usedin fabrication of the members of the entrance construction, a uniquecorner clip is employed that is welded directly to the members. Thetechnique of welding a stainless steel corner clip to the stainlesssteel members is unique in the present invention since in the priorknown aluminum door constructions, welding of corner clips was notusually resorted to because of the relatively low melting point ofaluminum. The corner clips as employed herein are also formed in aspecial shape and configuration to accommodate the interior lock seamsof the entrance construction members. Since the memhers that define theentrance construction of the present invention are formed of a stainlesssteel material, a unique technique is utilized for securing panelretainers in place. This technique involves the use of special retainerclips that are so constructed as to provide for the snapping into placeof the glazing or panel retainers. These special clips are furtherconstructed so as to enable the panel or glazing retainers to beadjustably positioned, thereby accommodating for panels or glazing ofvarying thickness.

Accordingly it is an object of the present invention to provide anentrance construction wherein the members However heretofore stainless.

United States Patent G ice 3,307,294 Fuentes Mar. 7, 1967 thereof areformed of a relatively thin gauge stainless steel material and are rollformed to define an interior lock seam.

Another object of the invention is to provide a metallic entranceconstruction wherein the members thereof are joined at the corners bycorner clips that are especially formed to accommodate lock seamslocated interiorly of the members.

Still another object is to provide a corner clip for use in an entranceconstruction, the corner clip being welded to the members that definethe entrance construction at the corners thereof.

Still another object is to provide an entrance construction havingmembers formed of a relatively thin gauge stainless steel material andincluding retainer clips that provide for the adjustable mounting ofpanel holding retainers.

Still another object is to provide a retainer clip for use in anentrance construction wherein the retainer clip is formed with laterallyoffset legs that provide for adjust ably mounting panel retainersthereon.

Other objects, features and advantages of the invention will becomeapparent as the description thereof proceeds when considered inconnection with the accompanying illustrative drawings.

FIG. 9 is an enlarged perspective view of one of the retainer clipsembodied in the present invention.

Referring now to the drawings and particularly to FIG. 1, the entranceconstruction embodied in the present invention is generally indicated at10 and includes a frame assembly generally indicated at 11 and a doorassembly generally indicated at 12 that is mounted for pivotal movementin the frame assembly 11. The frame assembly 11 which defines an openingin which the door assembly 12 is located includes an upper horizonalframe member 14 and vertical frame members 16 and 18. Since the entranceconstruction of the present invention is adapted to be utilizedprimarily in commercial installations, it is not necessary to provide athreshold for the frame although such a threshold may be employed if itis practical or so desired. As further shown in FIG. 1, additional framemembers 20 and 22 may be incorporated in the frame assembly and areconstructed and secured in place in the same manner as the members 14,16 and 18. Panels 24 formed of glass or other decorative material suchas plastic, metal or wood are secured to the frame members by anyconvenient means and may be mounted in place by a unique technique to bedescribed hereinafter in connection with the door assembly 12.

One of the novel features of the present invention is in the use of arelatively thin gauge metallic material that is adaptable for rollforming into a tubular construction. In the preferred form of theinvention, stainless steel is employed, but is formed of a relativelyreduced thick ness to define a thin gauge material, the thin gaugestainless steel being adaptable for roll forming into the tubularconfiguration of the members that cooperate to define the doorconstruction illustrated in FIG. 1. Referring to FIGS. 2, 5, 6 and 7 thetubular members that form the frame and door assembly of the doorconstruction are illustrated and as shown, these members have beenrolled to a tubular configuration and are interlocked interiorly thereofby a lock seam. In FIG. 2 the horizonal frame member 14 is showncomprising an upper wall 26, sidewalls 28 and 30 to which are joinedcoextensive bottom walls 32 and 34. The walls of the horizontal framemember 14 have been rolled to the configuration as illustrated in FIG. 2and the edges thereof indicated at 36 and 38 are interlocked in a lockseam which forms a longitudinally extending rib indicated at 40. Asshown in FIGS. 5, 6 and 7 the vertical and horizontal sash members thatdefine the door assembly 12 are roll formed in a similar manner to thatjust described and are also interlocked by an interior lock seam.

Referring again to FIG. 2 the frame member 14 is shown being secured tothe vertical frame member 18 by a corner clip that is generallyindicated at 42 and that is illustrated in detail in FIG. 3. The cornerclip 42 includes a base 44 to which an upper wall 46 and spaced bottomwalls 48 and 50 are integrally joined. The bottom walls 48 and 50 arespaced apart and thus accommodate the rib 40 of the lock seam formedinteriorly of the horizontal frame members 14. Communicating with thespace between the walls 48 and 50 is a slot that is formed in the base44 and that is also adapted to accommodate the lock seam 40. Openings 54are provided in the walls for receiving bolts therein that are employedfor securing the corner clip 42 to the vertical frame members. As seenin FIG. 2 the base 44 of the corner clip 42 engages a vertical surfaceof the vertical frame member 18 and is disposed interiorly of thehorizontal member 14 at the end thereof. Bolts 56 extend through thecoextensive bottom walls 32 and 34 of the frame .member 14 andthreadably engage the openings 54 formed in the walls 48 and 56 of thecorner clip 42. The corner clip 42 is thus firmly secured interiorly ofthe horizontal frame member 14. As seen in FIG. 2, the rib 40 thatdefines the lock seam of the frame member 14 is received within thespaces formed between the wall 48 and 50 and further extends through theslot 52 formed in the base 44 of the corner clip 42.

It will be noted that the space defined by the walls 48 and St issomewhat larger than the rib 40, but is constructed in this manner so asto enable the corner clip 42 to be universal in use; that is, it may bereversed in position when located in the horizontal frame member 22. Asfurther shown in FIG. 2 the corner clip 42 cooperates with both thehorizontal frame members 14 and 22 to lock these members to the verticalframe member 18. Thus bolts 58 extend through the openings formed in thebase 44 of the corner clip 42 and project through spacers 59 forsecurement to the base of the corner clip located in the oppositehorizontal frame member 22. The corner clips 42 in the frame members 22and 26 are thus, in effect, fixed to each other through the bolts 53 andsince the corner clips 42 are secured to their respective horizontalframe members, the horizontal frame members will then be fixed to thevertical frame member 18. It is understood that the horizontal member 14will be secured to the vertical frame member 16 and to the adjacenthorizontal frame member 20 in the manner as just described.

The door assembly 12 which occupies the opening defined by thehorizontal frame member 14 and the vertical rail or sash member 60, alower horizontal sash memframe members 16 and 18 includes an upperhorizontal ber 62 spaced from the upper sash member 60 and spacedvertical sash members 64 and 66 that are secured to the horizontal sashmembers 60 and 62 in the manner that will be described hereinafter.Although not shown, the door assembly 12 is mounted for pivotal movementon the frame by pivot elements that in the present invention would beconcealed within the horizontal sash members 60, 62 for securement tothe horizontal frame member 14 and to the floor. The door assembly 12 isthus adaptable for use as a center hung type of door, wherein the pivotelements therefor are spaced from the heel edge thereof and the door maybe pivotally moved in both an inner and outer direction. It isunderstood that the door assembly may be pivotally mounted by otherconventional hinging such as butt hinges.

As previously described in connection with the horizontal frame member14, the sash members 60, 62, 64 and 66 that define the door assembly 12are constructed of a metallic material such as a thin gauge stainlesssteel and are rolled formed into a tubular configuration as illustratedin FIGS. 5, 6 and 7. Although only the vertical sash member 64 and thehorizontal sash member 62 of the door assembly 12 are shown in FIGS. 5and 6, it will be understood that the vertical sash member 66 and thehorizontal sash member 60 are constructed similarly thereto and arerolled to the tubular configuration in a similar manner. The verticalsash member 64 includes a longitudinally extending outer wall 68 that iscurved in configuration so as to provide for the double acting pivotalmovement of the door assembly 12. Joined to the curved outer wall 68 areside walls 70 and 72 to which inner Walls 74 and 76 are integrallyjoined. Edges 78 and 80 of the walls 74 and 76 are respectively formedin a lock seam indicated at 81 in the manner as described in connectionwith FIG. 2, the lock seam 81 being located interiorly of the member 64as indicated.

The horizontal sash members 60 and 62 are also formed in a tubularconstruction and are roll formed to define interlocking lock seams. Asmore clearly illustrated in FIGS. 6 and 7 the horizontal sash member 62is shown including side walls 32 and 84 that are reversely bent to forminner opposed Walls 86 and 88, respectively, to which an inner web 96 isintegrally joined. Joined to the side walls 82 and 84 and bent at rightangles with respect thereto are the upper walls 92 and 94 the ends ofwhich are interlocked in a lock seam indicated at 96. As shown in thedrawings all of the tubular members that define the door assembly 12 andthe frame assembly 11 of the entrance construction 10 are rolled from aone piece sheet material to the tubular shape and are fixed in thetubular configuration by the interlocking of the edges in a lock seam.

Referring now to FIG. 4 and referring again to FIGS. 5, 6 and 7, acorner clip generally indicated at is illustrated, and as shown issecured to the corners of the horizontal sash members 60 and 62 and thevertical sash members 64 and 66 to lock their members in place in themanner as shown. The corner clip 100 is also formed of a stainless steelmaterial so as to be welded to the thin gauge stainless steel doormembers and includes a base 102 to which an offset portion 104 is joinedfor the purpose that will be described hereinafter. Secured to the base102 and extending perpendicularly with respect thereto is a vertical leg106, the vertical leg 106 being bent along the lines 108 and 110 asindicated, to form the leg in a generally curved or arcuateconfiguration. As will be described, this configuration of the leg 106accommodates the lock seam formed on a vertical sash member of the doorassembly. Secured to the vertical leg 106 is a horizontal leg 112 thatis also bent along lines as indicated at 114 and 116 to form the leg 112in a generally curved or arcuate configuration. This configuration ofthe horizontal leg 112 accommodates the lock seam that is formedinteriorly of the horizontal member to which the corner clip 100 issecured.

In order to secure the corner clips 100 interiorly of the door assemblymembers, weld openings are formed in the walls of the sash members sothat weld material may be introduced therein, the weld opening beinglocated so that the weld material will engage the base 102 and legs 106and 112 of the corner clip 100. Referring again to FIGS. 6 and 7 aplurality of openings 118 are shown being formed in the walls 74 and 76of the vertical sash member 64. An opening 120 is formed in the wall 94of the horizontal sash member 62 while an opening 122 is formed in theinner web 90 of the horizontal sash member 62. When the corner clip 100is placed in position within the horizontal and vertical sash members 62and 64 the surfaces of the portions thereof that are located oppositethe weld openings are adapted to receive weld material therein forsecuring the corner clip 180 in position. As shown in FIGS. 6 and 7,weld material indicated at 124 is deposited in the openings 118 tosecure the vertical leg 106 to the walls 74 and 76 of the vertical sashmember 64. The horizontal leg 112 is disposed beneath the lock seam 96and a weld material 126 deposited in the opening 120 engages portions ofthe horizontal leg 112 to lock this leg to the adjacent walls 92 and 94of the horizontal sash member 62.

The base 102 of the corner clip 180 is positioned on the upper surfaceof the inner web 90 and a weld material 128 is deposited in the opening122 and thus secures the base 102 to the inner web 90. Additional weldsindicated at 130 and 132 secure the base 102 to the wall 74 and 76 ofthe vertical sash member 64, and secure the olfset portion 104 to the'wall 68 of the vertical sash member 64.

When the corner clip 180 is secured in place as indicated in FIGS. 5, 6and 7, the horizontal leg 112 is positioned just below the lock seam 96of the horizontal sash member 62, the arcuate configuration of thehorizontal leg 112 accommodating the lock seam 96 as indicated.Similarly when the vertical leg 106 is located in the position asillustrated in FIG. 6, the arcuate configuration thereof accommodatesthe lock seam of the vertical sash member 64. It is seen that the oifsetportion 104 of the corner clip 100 in the assembled position thereof issubstantially level with the lower surface of the inner web 90 and thuscooperates therewith to receive a block or assembly that may be insertedwithin the horizontal sash member 62 from the underside thereof. Such ablock or assembly may include a pivot assembly or a closureconstruction.

The door assembly 12 also includes a glass panel 134 that is adapted tobe secured between the horizontal sash members 60, 62 and the verticalsash members 64 and 66. In order to provide for different thicknesspanels and to further firmly secure the panel 134 in place the presentinvention incorporates a unique retainer clip as shown in FIGS. 5A, 6A,8 and 9. Each of the members that define the door assembly 12 hasattached thereto a plurality of retainer clips generally indicated at136, the retainer clips 136 being located in spaced relation andcooperating with appropriate panel retainers indicated at 138 and 140for securing the panel 134 in position. Although only a single member isdescribed in connection with the retainer clip 136 and although onlypanel retainers 138 and 140 are referred to it will be understood thatthe other door assembly members are provided with similar retainer clipsand panel retainers.

Referring now to FIG. 9, the retainer clip 136 is shown in detail andincludes a first portion 138 that is defined by a central section 140,to which opposed legs are joined, the opposed legs being defined byinclined sections 141, 143, horizontal sections 142, 144 and elevatedend sections 146, 148.

integrally joined to the end sections 142, 144 of the opposed legs aredepending fingers 150, 152 which, as will be described, are provided forengaging opposing hook portions formed on the panel retainers 138 and140, wherein the panel retainers are secured to the retainer clips 136.

Joined to the first portion 138 by a central web 154 is a second portion156 that is constructed substantially identical to the first portion 138but that is offset with respect thereto. Thus the second portion 156 ofthe retainer clip 136 includes a central section 158 to which opposedlegs are joined. Defining the opposed legs are inclined sections 159,161, horizontal sections 160, 162 and elevated end sections 164, 166 towhich depending fingers 168, 170 are joined. As previously mentioned,the second portion 156 is offset with respect to the first portion 138,thus the finger 170 extends somewhat outwardly of the finger 152 andsimilarly, the finger eX- tends somewhat outwardly of the finger 168..The fingers of the first and second portion 138 and 156 are movable witha spring action with respect to the central sections 140 and 158respectively, this spring movement of the fingers being emphasized bythe securement of the retainer clip 136 to the door assembly members byspot welding the central sections 140 and 158 to the eX- posed surfacesof the members on which the panel 134 is mounted. Thus, as seen in FIG.8, the retainer clip 136 is secured to the member indicated at 62 bywelding the central sections 140 and 158 directly to the wall 94. Sincethe fingers of the first and second portions of the retainer clips areunconnected and are somewhat elevated, they have a certain amount ofresilience, which is further emphasized by forming the clips of a thinand relatively hard stainless steel material. The clips 136 are locatedin spaced relation along the length of each sash member so that thefingers 152 and 168 define an inner position for the panel retainers 138and 140 that are adapted to be mounted thereon. Conversely the fingers150 and 170 that extend outwardly beyond fingers 168 and 152,respectively, define an outer position for the panel retainers 138 and140.

As further seen in FIG. 8 the panel retainers 138 and 140 are formed ina configuration that generally defines a C-shape and include portions172 and 174 respectively that define grooves into which resilientsealing members 176 and 178 are inserted. Joined to the panel retainers138 and 140 are spaced from the portions 172, 174 are inwardly extendinghook portions 182 and 184 that are adapted to be engaged by the fingersof the retainer clip 136. The panel retainers 138 and 140 are adapted tobe inserted in place by the shifting thereof in a lateral direction. Thepanel retainers are thus located in a first position wherein the hookportions 182, 184 formed on the panel retainers engage the outermostfingers 150, 170 of the retainer clips 136. Thus the finger 150 of theretainer clips 136 will initially engage the hook portion 184 of thepanel retainer 140 and similarly the finger 170 will initially engagethe hook portion 182 of the panel retainer 138. Since the fingers 152,163 have a certain amount of resilience, they will be flexed upwardly asthey ride on the outer surfaces of the hook portions 182, 184 in thisinitial position of the panel retainers 138, 140. The glazing or panel134 is retained between the sealing elements 17? and 18d, and is mountedon a plurality of wood glazing blocks 186 that are located along thelength of the sash member 62. If the thickness of the panel 134, is suchthat additional adjustment is required, then either the panel retainer138 or 140 may be shifted laterally to force the hook portions 182, 184thereof to move into engagement with the fingers 152, 168 of theretainer clip 136. As seen in FIG. 8 the inner fingers 152 and 168 areshown riding on the outer surface of the hook portions 182 and 184respectively. Upon inner lateral movement of the panel retainer 138, forexample, the finger 152 will be moved into engagement with the hookportion 182, the engaged finger 1'70 accommodating this movement becauseof the resiliency of the leg to which the finger is secured. Similarlyif it is required to shift the panel retainer 140 inwardly foradjustment thereof, the inner finger 168 will ride off of the uppersurface of the hook portion 184 and into engagement therewith. It isunderstood that the outer finger 150 will accommodate this action due tothe resiliency thereof.

It is seen that the retainer clips 136 provide a unique manner ofadjustably securing the panel retainers 138 and 140 on the variousmembers that define the door assembly 12. It is also understood that thepanels 24 of the frame assembly 11 may also be secured to the framemembers indicated at 14, 18, 20 and 22 by incorporating the retainerclips 136 as previously described. Since the material from which thedoor assembly members are constructed is preferably stainless steel, theretainer clips 136 may be welded directly to the surfaces of thesemembers. However, if it is desired the retainer clips may be mounted inplace by the use of screws that extend through openings formed in thecentral sections 146 and 158 thereof.

While there is shown and described herein certain specific structureembodying the invention, it will be manifest to those skilled in the artthat various modifications and rearrangements of the parts may be madewithout departing from the spirit and scope of the underlying inventiveconcept and that the same is not limited to the particular forms hereinshown and described except inso far as indicated by the scope of theappended claims.
